Box C/D snoRNP complex Overview

GO Annotations consist of four mandatory components: a gene product, a term from one of the three Gene Ontology (GO) controlled vocabularies (Molecular Function, Biological Process, and Cellular Component), a reference, and an evidence code.


Summary
Small nucleolar ribonucleoprotein particles (snoRNP) with a role in pre-rRNA cleavage and in 2-prime-O-methylation of nucleotides at specific positions in rRNAs, snoRNAs, and other RNAs during maturation. The snoRNA present in the complex guides the site-specific 2-prime-O-ribose methylation by base pairing with the rRNA for 10 to 21 nucleotides immediately 5-prime of box D. The residue targeted for methylation in the substrate RNA invariably pairs with the fifth nucleotide upstream of box D in the guide snoRNA. The complex also acts to direct pre-rRNA folding and rRNA processing through base pairing to the rRNA or flanking precursor sequences.
GO Slim Terms

The yeast GO Slim terms are higher level terms that best represent the major S. cerevisiae biological processes, functions, and cellular components. The GO Slim terms listed here are the broader parent terms for the specific terms to which this gene product is annotated, and thus represent the more general processes, functions, and components in which it is involved.
